Preheat oven to 350 degrees. Line an 8Ă—8 baking pan with parchment paper or spray with nonstick spray.
In a small saucepan, gently melt chocolate and oil over low heat until smooth and glossy. Remove from heat and set aside to cool slightly.
In a small bowl, whisk together sugar and eggs 2-3 minutes, until the mixture is slightly lighter in color, and passes the ribbon test. Set aside.
In a medium bowl, whisk together the dry ingredients–almond flour, cocoa, baking powder, and salt.
When the melted chocolate mixture has cooled slightly, stir in the egg/sugar mixture into the saucepan of melted chocolate. Stir in vanilla and mix until smooth.
Stir in the dry ingredients and fold until just mixed.
Fold in the additional chocolate chips, reserving a few to sprinkle on the top, if you like.
Pour batter into your prepared pan
Bake at 350 degrees 20-24 minutes. A toothpick inserted in the center should only come out with a few moist crumbs.
Sprinkle with coarse salt, if using, and allow brownies to cool before slicing.
